For the sorrow that is according to the will of God produces a repentance without regret, leading to salvation, but the sorrow of the world produces death.
For the kind of sorrow God wants us to experience leads us away from sin and results in salvation. There’s no regret for that kind of sorrow. But worldly sorrow, which lacks repentance, results in spiritual death.
Can a woman forget her nursing child And have no compassion on the son of her womb? Even these may forget, but I will not forget you. Behold, I have inscribed you on the palms of My hands; Your walls are continually before Me.
